  • Product Detail:

    • Re-usable Edge Form to create a realistic Rock Edge on concrete.
    • "Granite Rock" top edge detail, 2 1/2" high.
    • This form is designed to be used right in place to make concrete steps, cast-in-place concrete countertops, pool surround edging, bars, fireplace hearths, seating benches, and more.
    • When using this form to make steps, the top cantilever overhang is 2.5" high rock edge detail, with smooth underneath part being 3 1/2" tall. 
    • Overall height @ 6"
    • When using as a countertop form, simply screw this form right to your cabinets for a re-usable, rock concrete countertop edge.
    • When using to make a pool surround, or cap to a wall, simply drill some small 1/8" holes through the rubber form, and use wire to a concrete stake and through the hole in the rubber, to secure form against the wall.
    • Made of extremely durable polyurethane that can flex and stay strong.
    • Cut to length easily with a utility knife or chop saw. Join cut pieces using silicone.
    • Good for hundreds of uses- Actually gets better with each use as they 'season'.

    Product Specifications:

    • Measurements:
      • Rock Edge portion: 89 1/4"L x 2 1/2"H.
      • Overall Rubber Liner: 5 7/8"H x 89 1/4"L x 1 5/8"Thick
    • Weight: 26 lbs.

    Mold Setup:

    • This Rock Edge Liner is designed to be secured in place by screwing through the thick bottom part of the rubber. Use washers with the screws to keep the screw head from sinking into the rubber.
    • Can be curved to form a radius edge, about an 18" Radius. If the Edge Form Liner begins to ripple and distort, then the radius is too tight, so you will need to make the curve radius larger to ensure a smooth, consistent edge detail.
    • Edge Form Liners can be cut to fit your form. Cut using a SHARP razor knife, or with a chop saw. Liners can be cut straight, or mitered at angles.
    • Use of a Rubber Safe form release is recommended, or use a colored dry powder release to create accented concrete color. Form release will create a smoother finish on the concrete, less air pockets in the concrete edge, and easier to clean the Edge Form Liners when finished.
    • Vibrate concrete well (either vibrating the concrete, or rapidly tapping the edges of the forms with a hammer or palm sander), or use your fingers to compact the concrete against the Form Liner to remove as many air pocket voids as possible.
    Edge Liner Removal:
    • After the concrete is sufficiently set up, remove the Edge Form Liner by slowly pulling it away, starting on one end and working down the length of the Edge Liner.
    • If the Edge Form Liner needs to be removed before the concrete is cured (usually only when using on cast in place concrete, such as steps or pool decks), make sure to remove edge slowly, evenly pulling the liner 'out' away from the concrete.
    • Concrete may will have small 'bumps' which can be sanded off with a 200 grit sandpaper. These bumps tend to disappear the more the Edge Form Liner is used, as it becomes seasoned.
    • Fill any air pocket voids with a Cement Slurry Mix.
    Edge Liner Care:
    • Clean with a stiff brush and water after each use. Any silicone left on the forms should be peeled or scraped off (the sooner the easier to remove). Any hardened concrete and difficult to remove silicone can usually be removed using a wire brush.
    • Muriatic Acid can be used to clean of cement residue from the Edge Form Liners in a 20:1 ratio (20 parts water to 1 part muriatic acid). Rub the Edge Form Liner with a stiff nylon brush and the muriatic acid water. Rinse Form Liner thoroughly with clean water.
    • Store Edge Form Liners out of direct sunlight, laid out flat.
    • If Edge Form Liners ever get curved or twisted so they don't lay flat naturally, the easiest solution is to lay them out flat on a concrete or asphalt surface on a really hot day and let the sun heat them up, straighten them out, and then when they cool they should hold their shape more naturally.
